Louis van Gaal says he has injury concerns over Phil Jones and Ashley Young following the 2-1 win over Swansea at Old Trafford.

Jones was replaced with Matteo Darmian at half-time while Paddy McNair came on for Young in the second half.

Van Gaal revealed Jones picked up an injury similar to the ankle problem that forced him to miss five games before Christmas while Young's withdrawal was a consequence of the busy fixture list over the festive period.

He said: "(Phil Jones) is injured. It's more or less the same injury he had last time. Ashley Young has played a lot of matches in a row and he is stiff and had to be changed. It was not voluntary. I changed because I had to change."
